Loxley gRPC Web

Using the DB as the source of truth for grpc-web automatic resource binding in a TypeScript frontend

Backend

• use sea-orm to write migrations
• use sea-orm-cli to generate serde rust structs
• write serde rust structs to protobuf schema /protos
  • for now, write custom services for those protobuf schema
  • could have CRUD endpoints autogenerated in future and then add custom ones for other data
• use tonic(-web) to serve data via grpc-web endpoints
  • can ignore unimplemented endpoints with a simple return Err(Status::unimplemented(message: impl Into<String>));
  • requests will require some protobuf <-> sea-orm serialisation

Frontend

• use npx protoc to generate grpc+protobuf interfaces, class, messages and bindings, making for a strongly typed db-led way of performing server calls
  • npm run build:protos
• use protobuf-ts send data via gRPC-web
